Hello guys!

So I have this problem that recently came up in my track car.

With the engine on and while being on idle and the vibration of the car, the ABS light was blinking intermittently like there was a grounding problem. I took out the car for a few laps on the track and at some points the light was constantly on and at some other points it will be completely off, it all depended on acceleration or cornering movements.

Took the car back in from the session, and the light is completely on and steady.

That same day I took the car out again for the 2nd heat with the light completely on and I ended up locking some tires and damaging them with some flat spots that had to throw the tires to the garbage.

I connected the scanner so it could give me some codes and so that I could attack the problem easily, but the scanner will not read any codes!!

Rewinding back: Here is probably one the problem and it was my bad and mistake.

Right next to the emergency brake handle are 2 sensors, I thought that these 2 sensors where from the airbags which I don't have anymore and result that these are the G sensors for the ABS system!!! Ok here it goes, From one of the sensor I took power for a Auto Meter Volt gauge and on the other sensor I took power for a Cool Suit system, I didn't knew they were related to the ABS before connecting those accessories to them. These were working fine until the night after the event that I was checking everthing on the car, the gauge and the cool suit cooler where not working anymore, and there is now NO power on those cables I took the power from the sensors.

I bought on Ebay 2 new sensors just in case I busted them up, but the thing is, that there is no more "power" out of those wires that go to the sensors plug.

What in the world could the problem be? Where are the fuses located for the ABS system?

Thanks in advance guys!

 

blow fuse or fusible link. I believe the fuse for the ABS is in the under hood box near the driver side of the engine bay, if not its located behind the lower left dash panel.

 

you probably fried the abs module, if none of the fuses are blown.

 

Did you look at the abs wire on the caliper? It could have melted or rubbed the wires. I had that happen and i would get intermittent abs light on. The wires were just exposed and touching every now then then. Not sure why you have no power from the sensors but it might have fried them too.

 

If your at a event and have a problem with the ABS just pull the fuse and run without it.

 

We are going to check all of the fuses in the car Thanks

Man I have been thinking that...

This has happened before, but now is not the case. Thanks anyways!


Thanks for chiming in guys, really apprecitate your help.

 

You think it will have the same stopping power? One has to be very gentle with the pedal because of locking the tires! Which happen to me already.

 

There is a 7.5A fuse that feeds those sensors. Fuse 12 in the junction block on the '03. Not sure if it's the same on other years.

Looking at the schematic, if you wired it into the high side properly and didn't do anything funny to the output lines on the sensor, the module is likely OK.

Either way, wire the stuff into something else that is not critical and has excess capacity.

 

Thanks for your input! I hope the module is OK, I ordered a used on Ebay today just in case... Are those metal lines that plug on to the module easy to remove and re install on the new module?

Where is that 7.5 fuse you are talking about, on the fuse box located on the engine bay or the one inside the car close behind where you open the hood?

Thanks man!

 

mine is an 03'

 

I admit ABS can save a set of tires from flat spotting but you should learn to threshold brake without ABS. When it is wet I always run without ABS. I want to know were the grip is under braking. ABS will not stop the car if you go off course on gravel or wet grass. Charlie wanted to take it out when we changed to a pro balance bar set up.I had to insist we keep ABS in the car to save tires on bumpy tracks. I have a switch on the dash to turn the ABS on or off during the fly.

 

I dont think your window net is protecting you.

 

Mike is right, the +12v comes straight from the fuse block not from the abs module. my bad.

 

What a dilemma! I need those ABS mentally lol... Your setup sounds good! Will consider.

It was during a practice session, otherwise the marshall would not let me go out during a race! The net goes a lot further down.

Thanks anyways bro.



I will give some updates when I have some, thanks guys!

 

Evos with ABS doesn't have in line restrictor to control rear brake bias. It uses ABS to control rear bias. Where as evo rs doesn't have abs and has inline restrictor to control rear bias. So if your abs is not working, then your would get more rear bias then you would want.
